Running demos/downloads?

[Tofudude]

Hello.
(im a noob so sorry if this is a basic question...)

I am trying to run a psp demo that I downloaded (Pixeljunk Monsters Deluxe to be specific) in JPCSP. I put the file in ms0>PSP>GAME...and when I try to run it with the "load memory stick" option I get an error saying something about an unsupported file type...what is wrong? Are PSN downloads even supported in JPCSP?

Thanks

PSN downloads and DLC content are DRM signed, which is one of the most used encryption schemes employed by Sony.
This hasn't been fully reverse engineered yet, so no public standalone decrypters exist (you can use your PSP to decrypt this content just fine).
